Silicones That Work

Specialty Silicone Products (SSP) submitted samples of two 40-durometer military / aerospace silicones to independent ISO 17025 accredited test laboratories. These samples were tested against commercial and military standards.  SSP-220 met the physical and mechanical requirements of A-A-59588, Class 2A and 2B, Grade 40. SSP-267 met MIL-DTL-25988C, Type 2, Class 2, Grade 40 physical requirements. The following sections describe the products and summarize the test results.  [...]

Specialty Silicone Products (SSP) has developed a 50-durometer silicone that meets the full requirements of A-A-59588, Class 3A, Grade 50. The elastomer, SSP-2523-T, combines low-temperature resistance with high tear strength and flex-fatigue resistance. SSP-2523-T is supplied as uncured ready-to-mold compounds, compression-molded sheets, and continuous rolls for gasket fabrication. A-A-59588, Class 3A and Flex-Fatigue Resistance The A-A-59588 standard is published by the U.S. General Services [...]

Specialty Silicone Products (SSP) supplies 50, 60, and 70 durometer silicones that meet the full requirements of the A-A-59588 3B specification – with no exceptions for flexural testing. Other suppliers may claim to meet this requirement, but industry-wide compliance has been inconsistent. The 50, 60, and 70 durometer silicones that SSP supplies have been tested and certified to the full A-A-59588 3B specification, which includes DeMattia Flex Test requirements for resistance to [...]

Silicones resist a wide range of service temperatures, but they don’t always offer strong flex-fatigue resistance – a measure of an elastomer’s ability to withstand repeated flexing or bending. Flex-fatigue resistance is an important requirement for military and aerospace applications, however, so design engineers and technical buyers need to source silicone rubber with care. High temperatures, harsh environments, and excessive cycling can also contribute to elastomeric [...]

Specialty Silicone Products (SSP) supplies M83528 gasket materials and a full line of silicones and fluorosilicones that meet military and aerospace requirements. Specifically, SSP provides compounds that are fully tested to MIL-DTL-25988C and A-A 59588 standards. Converters, gasket fabricators, and aerospace and defense contractors can also choose SSP compounds that meet SAE AMS 3326 requirements. MIL-R-25988C Fluorosilicones MIL-DTL-25988C is a U.S. military specification (MIL-SPEC) for [...]
